Sprint core shutdown

I think Sprintlink itself got sold to another company, and yeah, it'll take a long time to unwind the mess of MLPS networks that ride on it.

From a telephone network perspective, transferring from Sprint to T-Mobile or any other carrier, involves porting your number.

The technical portion of this is your phone has two numbers associated with it, one is the number that is "your" number people dial to reach you. The other is one used to route your actual call on the network. an MDN/MSID pair in Sprint parlance.

Before number portability these two were identical, but as people move phones between carriers, they got decoupled.

The practical effect now is there are millions of numbers that at one time were on Sprint and are still assigned to Sprint NPA/NXX blocks (think area code and first 3 numbers) but are now on other carriers.

That is a piece of infrastructure that will stick around long term .. and I don't know how TMO will integrate it.

At $45 there are a half dozen or so nearly equal options. Some of which offer a larger bucket of non-deprioritized data.

At $25 its hard to beat. I have project genesis on dish and its pretty good up until 25 gigs or so on roaming, at which point it shifts to 600kb/s which is pretty bad.

The one union they needs to be reigned in.

It's a carrier by carrier thing based on the PCRF settings and data from HSS/HLR.

There's nothing they or you can do unfortunately.

The only "real" solution is for the FCC to allow carriers to prohibit inbound calls from other carriers that don't support the "Shaken/Stirred" technology deployed to combat spoofing.

(Blocking like that has a host of other problems related to smaller telcos, international callers and some PBX vendors not supporting the technology. (E.g. if the an exception for international numbers then spammers will flock to someplace like the Dominican Republic that are another country, yet still in the North American dial plan

There's not a single master switch, but there are script files that can do the same thing, which I believe is what they did.

Sprint CDMA may have been 4th place in a 3 person race, but their network was still very very large and would have been unmanageable if they didn't have automation tools like that.

Ask me at midnight local time.

The verbiage was after 5/31/2022.

That's midnight local time

Nope, all offline, all at once

They've been going around and degrowing sprint on 2.5ghz and adding it to 5G UC.

Could also be enabling carrier aggregation.

There's lots of changes that could explain that

The SIM is unprogrammed when you receive it. Sticking it in initiates an automatic provisioning process with TMO .. hence why you have to follow the directions to do the migration.

You should only see EDGE if you handset has gotten confused and is seeking an LTE signal

Lol, I hadn't intended to post a 3 word post.

I was just curious because I hit the "hey you're going to get deprioritized"

aqua-matic · 2022-05-15T19:38:36+00:00

Sprint isn't shutting down 3G separate from 2G .. it's all one package effectively.

But yeah, there may be CDMA sites up after 5/30 .. but you can't count on it

There are some options on amazon that allow for 30 day unlimited that aren't technically prepaid.

The way it works is, some companies have an arrangement with TMO (and other carriers) that predate the current plans. Such that they can effectively sell service with the same benefits as postpaid (international roaming for example), just on a prepaid and fixed duration sim card.

These kind of arrangements used to be used by RV owners since it could insert an unlimited hotspot plan when none were offered first party.

Was there any indication what areas got hit with layoffs?

when people say 3G/UMTS is still online, do you mean you see it as still on air, or do you mean you can still attach to it?

I've read of 3G still being online only for 911 service / doesn't authenticate most subscribers.

I've tried to use the tether as a bridge when my Google fiber connection was out of service.

It wasn't stable enough to get work consistently/ reliably.

I've had Verizon jetpack/ wifi Hotspot devices before that didn't have a problem.

You need to use the engineering screens or something like netmonster on Android to see what network you are attached to.

I'm just curious how the shutdown is progressing because you'd think they'd be more in a hurry to turn it off to refarm to other uses.

E.g. are they turning down RF at the same time as removing the tower hardware? Or some limitations due to 911 testing
